@Sinada Agreed. This is really frustrating. Just like the other question with Pat and the video store coupons.

I assumed based on past lessons that that the grammar parsing was key to these questions. And these last two questions feel like the test is baiting you with the words like guarantee or establishing rules and having the answer be outside of the rules you expect.

I get it, that's how the test is designed to trick you, but it's still frustrating since there are other times where guarantee does mean something that is part of a more logically rigid stimulus. I guess this time it feels like it came out of nowhere.
